Crystal Castles, Phosphorescent Hit Late-Night TV

Watch Crystal Castles on "Kimmel" and Phosphorescent on "Letterman"

Crystal Castles' live show works so well in part because it's a total sensory overload. The band performs in the dark, with a hyperactive strobe light blasting throughout; half the time, you're not sure what you just saw. And even though the set at ["Jimmy Kimmel Live!"](http://abc.go.com/shows/jimmy-kimmel-live ""Jimmy Kimmel Live"" ) has more of a stage-light setup than most live shows, you're just not going to get anything like the full power of the band's live presence.

But when the group stopped by the show last night to perform their song "Baptism", we did get to see Alice Glass brandishing a lollipop like a weapon and fearlessly scaling the drum set, which is definitely something. Besides a few tentative fist-pumpers, the audience either point-blank hates the Canadian electro-punkers, or they're absolutely terrified of them. Either way, a pretty mesmerizing few minutes of TV.

In other late-night action last night, roots-rock ramblers Phosphorescent hit the ["Late Show With David Letterman"](http://www.cbs.com/late_night/late_show/ ""Late Show With David Letterman"" ), playing ["It's Hard to Be Humble (When You're From Alabama)"](http://pitchfork.com/reviews/tracks/11828-its-hard-to-be-humble-when-youre-from-alabama/ ""It&squot;s Hard to Be Humble (When You&squot;re From Alabama)"" ). Letterman's joyous reaction is pretty great. That video is also below, via Prefix.
